Trying to give my 'Holsworthy Boys' estimated dates of enlistment. The majority of the 36 I've managed to do but am having some difficulty with the following.

Can anyone give me some idea of estimated enlistment dates for the following numbers/Regiments?

41 Coy Machine Gun Corps - 128325

6th Batt Royal West Kents - 241216

16th Batt Devon Regt - 345728

8th Batt Devon Regt - 15569

1st Batt Devon Regt - 265409

2/7th Batt Worcesters - 202121

1/4th Batt Ox & Bucks - 202499

ASC - R/258377

With grateful thanks and kindest regards
